I have one of the cameras that this product is said to work for, no more battery charging or swapping. Well, of course, that means tethered to the AC outlet, which is what I wanted, power to use my old camera to record long videos, in high def.It works well, but no instructions stating anything, no instructions included. The plastic battery cover must be removed AND some method must be employed to keep the battery cover metal hinge closed, and only then will it power up the camera.The camera will not work with the battery installed and the door open, so this is no fault of this product. I am looking for another old used camera and will buy another one of these, for multi-angle shots.
